Question

Select the correct answer.Consider these functions:What is the value of x when g(h(x)) = 4?

Answer 1

Given:

Here in question,

we have two function with their image

Required:

We need to find the value of x when g(h(x)) = 4.

Explanation:

for this first of all as we can see that the image of 2 in g is 4 so here we can say that

$\begin{gathered} g(2)=4 \\ g(h(x))=4 \end{gathered}$

so h(x)=2

now at x-4 we have h function 2 so the value of x is 4

Final answer:

We get g(h(x)) = 4 when x=4
